Editor’s Pick. Jeffrey’s novels, like the universe itself, tend toward the expansive, and The Light Within Darkness feels bigger than ever. . . . The action is brainy but still visceral, rendered in crisp prose, with stakes that couldn’t be higher. But the heart of this series is in teamwork, in singular solutions to intractable problems, in impossible dilemmas and hard choices . . . Takeaway: Stellar space-faring SF bursting with new worlds and camaraderie.

The third installment in David C. Jeffrey’s Space Unbound saga continues the rousing, grand-scale science-fiction adventure featuring commander of the Sun Wolf Aiden Macallan and his crew . . . The storyline is filled with more than a few wildly satisfying plot twists, which not only enrich the novel but plant fertile plot seeds for upcoming installments. Bottom line: Jeffrey’s stellar saga is just as good—if not better—than anything grand-scale science fiction fans will find currently being released by traditional publishers. It’s a stand-up-and-applaud, unforgettable reading experience.
